Room temperature sputtering deposition of high-haze Ga-doped ZnO transparent conductive thin films on self-textured bio-based poly(ethylene 2, 5-furandicarboxylate) substrates

ABSTRACTZn0.90Co0.10O and Zn0.85[Co0.50Fe0.50]0.15O targets were used to grow thin films by rf magnetron sputtering. XRD patterns of the films showed a strong preferred orientation along c-axis. Zn0.90Co0.10O film showed a transmittance above 75% in the visible range, while the transmittance of the Zn0.85[Co0.50Fe0.50]0.15O film was about 45%; with three absorption peaks attributed to d-d transitions of tetrahedrally coordinated Co2+. The band gap values for Zn0.90Co0.10O and Zn0.85[Co0.50Fe0.50]0.15O films were 2.95 and 2.70 eV respectively, which are slightly less than ZnO bulk. The Zn0.90Co0.10O film showed a relatively large positive magnetoresistance (MR) at the high magnetic field in the temperature range from 7 to 50 K, which reached 11.9% a 7K for the magnetoresistance. The lowest MR was found at 100 K. From M-H curve measured at room temperature shown a probable antiferromagnetic behavior, although was possible to observe little coercive field of 30 Oe and 40 Oe for Zn0.90Co0.10O and Zn0.85[Co0.50Fe0.50]0.15O films, respectively.

AbstractFollowing the theory, ferromagnetism is predicted in Mn- doped ZnO, Indeed, ferromagnetism above room temperature was recently reported in thin films as well as in bulk samples made of this material. Here, we have prepared Mn doped ZnO by electrodeposition. The samples have been characterized by X-ray diffraction and spectroscopic methods to ensure that the dopants are substitutional. Some samples exhibit weak ferromagnetic properties at room temperature, however to be useful for spintronics this material need additional carriers provided by others means.

Quartz crystal microbalances (QCM) are transducers for chemical and biochemical sensing. The oscillation frequency of QCM is affected by the adsorbed mass on the surface. In this work, a new room temperature type gas sensor device fabricated by organically hybridized plasma deposition of tetramethyltin (TMT) and oxygen. Post treatment with poly ethylene glycol (PEG) was developed to detect the ambient environmental smother, and the responses of the fabricated sensor to smother detection were investigated. SnO x C y thin films on the sensor electrodes were obtained by plasma deposition from TMT and O 2 gas mixtures at room temperature. A spin coating post treatment on the SnO x C y thin films turns into hydrophilic property. The response of the QCM sensor to the smother detection shows a frequency drop during the burning of candle and has good detection sensitivity with Δf equal to 2400 Hz. Repeated smother testing with the QCM type smother detection sensor also indicates the stability of the fabricated sensor.
